Final answer:
Allergies and autoimmune diseases do not result from an over-reactive immune system. Allergies are a reaction to harmless substances, while autoimmune diseases involve the immune system attacking the body's own cells and tissues.
Step-by-step explanation:
False. Allergies and autoimmune diseases are not the same and do not result from an over-reactive immune system. Allergies occur when the immune system reacts to harmless substances like pollen or pet dander, while autoimmune diseases happen when the immune system mistakenly attacks the body's own cells and tissues.
For example, in allergies, the immune system releases chemicals like histamine in response to an allergen, causing symptoms like sneezing, itching, and watery eyes. In autoimmune diseases, the immune system produces antibodies that attack the body's own organs or tissues, leading to conditions like rheumatoid arthritis or lupus.
Understanding the difference between allergies and autoimmune diseases is important in diagnosing and treating these conditions correctly.
